First time using a spot meter help needed
Today was my first time using a spot meter and need advice on if i did it correctly. I metered the sky, the front door and the water and then averaged them to get this exposure. I thought i would meter the brightest of the sky down to the dark water. Did i do this right and does anyone have advice on a better way of metering the scene? Below is a scan of the negative. The film is Efke 25 and i used a Pol filter and shot the scene @ 6 iso to make up for the pol filter.
If you are satisfied with the results, then you did alright.
What is a master but a master student? And if that's true, then there's a responsibility on you to keep getting better and to explore avenues of your profession.
For a first time effort the image looks superb, assuming you have not fundamentally altered exposure during the scan process to put it up here on APUG.
Essentially, metering off a highlight, mid-tone and shadow around the key subject will give you an ideal basal exposure. The tipping point can be the sky; often it is 2-3 stops over the basal readings, meaning over-exposure there is a given. This means if the sky is largely featureless, then it can be foresaken for correct exposure of the key elements of the image. If the sky is moody, overcast and atmospheric, it must be included in its richness of detail, and spot metering here of highlights and mid-tones, along with the rest of the image done likewise, will bring up a well-balance image.
This image is symmetrically very pleasing to the eye. The trees (firs?) are eyecatching. And that's a real nice house you have there.
Averaging the spot readings does take into account the actual subject brightness range----you should read the darkest area of the scene that you wish to retain texture/detail and then the lightest area and then set the meter halfway between those readings. Most that use a spot meter will base the exposure on "placing" the most important shadow area i.e., one stop minus the reading, two stops minus the reading, etc...Then, will read the important high value and see where it "falls" relative to your placement of the shadow area---development is then decided upon given where the high value falls on the gray scale. It's all basic Zone System stuff, there's plenty of info out there from which to learn from if you choose. Like Rick A. said though----if you find that you are satisfied with the final result with "averaging" the low and high values, then roll with it. If you find you like your shadow areas but are unhappy with how the high values are being rendered, then I would suggest some deeper learning and use that spot meter in a more ZS like fashion.
Thanks for the helpful information. I was planning to read up on the Zone System but i was told it only works if your processing single sheets (large format), i shoot medium format 6x7.

You don't have to process each shot differently to use the Zone system. Of course there is limit to what you can do if you are forced to process all frames the same. I found the Zone system is useful for knowing what you are going to get in the final result before taking the shot. How much controls you have on this respect depends on whether you process 1 frame at a time, shooting B&W or color or you shoot transparency. But with good knowledge of the Zone system you know what your final image will look like.
The Zone System is most effective with sheet film, but that doesn't mean you can't apply it, at least partially, to roll film. I usually try to keep track of my exposures, and then develop for either the majority, or the most important exposures on each roll. Sometimes, I'll load two roll film backs for my RB67 with the same film, and use one for high contrast scenes, and the other for low contrast.
Edit: As usual, I've been beaten to the point.

ZS might be appropriate (but not a be-all and end-all) for large format, but it is not, nor universally, just that.
Peoplel are turning up beautiful photographs in any format not necessarily following fond orthodoxy.
Smaller formats are a bit more restrictive, but it's entirely relevant. There's a book that details how to use the ZS with 35mm, can't recall the exact title or author though------"expose for the shadows and develop for the highlights", in a nutshell that's what the ZS is based on---it's just a more refined and methodical application of that old maxim, and large format photography, of all the formats, is capable of making the most of it.

So, in my opinion, a modified Zone System is entirely relevant to and useable with roll film.
Now, to the OP's original question: The big advantage of a spotmeter is that you can use it to deal with two very important shortcomings of averaging meters, 1) making sure the shadows have enough exposure and 2) measuring the subject brightness range. This latter is more important when one has control of development for each photograph, enabling one to develop each image to the contrast so it prints as desired. With roll film, this is less of an issue, and contrast is usually dealt with by changing paper grades at the printing stage.
The first issue, shadow placement, however, is still of prime importance. So, if I were you, I'd read up on enough of the Zone System to understand shadow placement and the associated film speed test (easy to do with roll film, BTW, a lot easier than with sheet film). In essence, however, all you need to do to start is measure the shadows that you want to contain detail (i.e., not just be featureless black) and then give 2 stops less exposure than the meter indicates. This will get you going till you become more sophisticated with placing values.
If you want to get the most out of your spot meter, then do use it to measure important shadows and place them properly. The problem with averaging, as mentioned above, is that if the subject is very contrasty, an average exposure of high and low readings will severely underexpose the shadows. Placing the shadows ensures that this does not happen. With my method, you don't even have to bother metering the higher values (but you certainly can, for curiosity's and learning's sake).
Somewhere here I have expounded a "Zone System for roll film users" that eliminates the need for a lot of different development times. It standardizes on a less-than-normal-contrast development and paper-grade changes to deal with contrast. Maybe a search on my name will turn it up. If not, and you are interested, PM me and I'll send it to you.
